public PolygonCodec(CodecRegistry registry)

Constructs an instance.

Parameters:

registry - the registry

Method Detail

encode

public void encode(BsonWriter writer,
                   T value,
                   EncoderContext encoderContext)

Description copied from interface: Encoder

Encode an instance of the type parameter T into a BSON value.

Specified by:

encode in interface Encoder<T extends Geometry>

Parameters:

writer - the BSON writer to encode into

value - the value to encode

encoderContext - the encoder context

decode

public T decode(BsonReader reader,
                DecoderContext decoderContext)

Description copied from interface: Decoder

Decodes a BSON value from the given reader into an instance of the type parameter T.

Specified by:

decode in interface Decoder<T extends Geometry>

Parameters:

reader - the BSON reader

decoderContext - the decoder context

Returns:

an instance of the type parameter T.

getEncoderClass

public java.lang.Class<T> getEncoderClass()

Description copied from interface: Encoder

Returns the Class instance that this encodes. This is necessary because Java does not reify generic types.

Specified by:

getEncoderClass in interface Encoder<T extends Geometry>

Returns:

the Class instance that this encodes.
